Learn the Positive Aspects of Precision Machining?

Some engineers recommend much tighter tolerances than are actually necessary when designing items. That’s not the best strategy. If a tolerance of +/-0.05mm is sufficient, choosing +/-0.01mm will significantly raise the cost of production. However, precision machining accuracy and consistency are unmatched when tolerances as small as 0.01mm are required.

High-precision grinding machines are also available at the 3ERP prototyping facility. The optimum application for this technique is the production of very accurate metal parts and prototypes. The action of grinding involves removing material from a workpiece until it has the desired form and specification using a spinning wheel made of bonded abrasive particles.

Similar to Precision grinding and wire EDM are optimally used to create small metal parts and larger parts with tighter tolerances, such as parts for scientific instruments, medical equipment, aerospace parts, and more.

How Can I Tell Whether My CNC Machine is Precise?

The phrase “positional accuracy” is used to define the precision of a CNC machine. It is calculated by setting the machine to move to a specific value and recording any variation from that value. The statistical average value of the deviations is determined after several readings are taken, and this number represents the machine’s positional accuracy. The typical figure for the majority of CNC machines is 0.02mm. Your machine is probably not accurate if your value falls outside of the range.

Reason for Choosing 3ERP

There are a ton of companies that offer precise machining. Why ought you to pick them? The top 3 explanations are as follows:


Their experts can handle complex and precise parts in a variety of sectors with ease because they have accumulated deep, rich experience from numerous prior projects.

Modern Devices

There is a lot of equipment for testing and manufacturing at 3ERP. Our cutting-edge in-house machinery, which includes Hexagon, EDM, and precision CNC milling CMM, likewise an Olympus XRF analyzer, will be used to produce and inspect your parts.

Rapid Reaction

We typically respond to bids within 24 hours, ship components in 7 days or less, and have a 99% success history for on-time delivery and quality.

Advantages of Precision Machining

Precision machining is a crucial step in the manufacturing process, enabling businesses to create the most delicate parts with the most exacting tolerances. Here are only a few of its primary benefits over other strategies:

High Accuracy

Precision molding, as the name suggests, offers unmatched accuracy and consistently high quality with every component manufactured.

Minor mistakes

Precision machining is largely automated and has a very low chance of error because it uses CNC technology.


Precision CNC machining can produce parts very effectively and with little help from the labor due to the automated nature of the operation.

Reduced Waste

Precision machining generates the least amount of waste, allowing for material cost savings and the maintenance of green manufacturing techniques.


The process’ high-tech nature also results in less waste, less labor, and a lower risk of error, making it one of the more economically efficient manufacturing processes.

Tolerance for CNC Precision Machining

Despite being extremely accurate, precision CNC machining tools cannot precisely duplicate a product’s dimensions as they appear in the CAD layout. Tolerances are therefore used by machinists.

The deviation in a part’s dimension is within tolerance and is considered acceptable by industry standards. Dimensional correctness is a term that describes it. Precision CNC tolerance does not have a set norm. The manufacturing process determines how rigorous of a tolerance to use. The degree of precision in the measurement is indicated by the number of decimal places in a tolerance value.

Bottom Line

Precision machining removes superfluous raw material from a workpiece while retaining close-tolerance completion in order to create a finished product. Essentially, it refers to the procedure of slicing large quantities of material into smaller, more precise pieces that may satisfy highly stringent requirements. This process comprises cutting, milling, turning, and electrical discharge machining, and it frequently requires the use of CNC machinery.
